Environmental and technical and economic indicators of methods of solid domestic waste recovery

Abstract

The paper analyzes the waste recovery methods. The comparison of the recovery and processing technologies of solid domestic waste is made. The most effective technologies are proposed from the point of view of ecology, specific capital investments, profitability. Analysis of the research results showed that the pyrolysis technology for the neutralization and recovery of domestic waste is the best according to technical and economic and environmental indicators. The calculation of the economic pay-back is carried out using the example of the waste recovery plant construction by the pyrolysis method in the Arkhangelsk region. The calculation took into account all costs associated with the construction and operation of the plant, including capital investments, maintenance and removal of waste, as well as their storage. At the same time, the item of income was formed both at the expense of obligatory of the Arkhangelsk region resident payments for the domestic waste removal, and at the expense of additional financial revenues from electricity and secondary resources (slag, pyrolysis oil, pyro-gas) generated during the recovery process. The project payback period was 7.8 years.
